What are the advantages of a small pluggable (SFP) port for a Gigabit Ethernet switch? How do I connect the four SFP ports of a d-link DGS 1248 t smart switch? I think the main advantage of the SFP port is the flexibility to connect to the network. The SFP port is a hot-swappable input/output device that can be plugg

The SFP is the abbreviation for the small FORM pluggable and can be easily understood as an upgraded version of the Gbic. The SFP module is half the size of the Gbic module, and can be configured with more than one port number on the same panel. The other features of the SFP module are basic and gbic consistent. Some switch vendors call the

These days, when HP acquired H3C, it was rare to see 3COM with 3 O-markers. But the problem, a year ago a project bought a 3COM switch 2924-SFP plus switch (PS: pure switch, no readable data). At that time saw a default management IP in the back, so log in to the Web interface configuration can be. Later the project bought H3C S5500 switch, do not have this switch, so idle.Due to the recent equipment is more tense, need to enable, the problem came, bu

How to disable the SFP module on H3C vswitches and other devices? The following warning is displayed: OPTMOD/4/PHONY_MODULE: GigabitEthernet1/0/2: This transceiver is NOT sold by H3C. h3C therefore shall NOT guarantee the normal function of the device or assume the maintenance responsibility thereof! This is a warning when SFP module is used on H3C vswitches, routers, and other devices. It generally means t

Stm32f103 DAC study notes Recently, I am working on the current-type signal output project and encountered some problems. Here I will take a note of these solutions for future use. This part of the Manual is not detailed, so we also encountered some resistance in use. A 64-core package is used. The reference vref + of this core ADC is the same port as the power supply, and vref-shares the power supply location. When the Active Value of the battery

The STM32 DAC module ( digital/Analog Conversion module ) is a 12-bit digital input, voltage-output DAC. The DAC can be configured in either 8-bit or 12-bit mode, or it can be used with a DMA controller. When the DAC is operating in 12-bit mode, the data can be left-justified or right-aligned. The

In some cases, for example, if you want to use DAC to output a sine wave, the simplest idea is to use a Timer for an interruption and assign a new value to the DAC during the interruption, and the DAC conversion is triggered. In this way, there will be some drawbacks. For example, in a complex system, there will be many interruptions, and Timer's interruption pri

few microcontrollers include a DAC. Although you can easily find a inexpensive DAC to control from your microcontroller, you can use, unused peripherals inste Ad of adding parts. Fortunately, you can convert a microcontroller ' s ADC channel along with a GPIO (general-purpose input/output) pin to a D AC. You can make a DAC by charging a capacitor to an analog lev
